The column and Vv'following description ymede'V inconnection 60y soy base 6 is formed'vvith anfnpper flatportionV'suppo'rting the channel `member 8 which er;-

tends between the iside frames andfxvhichi is 'held in rplacebyhzlvinganapertnre therein lfitting` over lan ups `ending k lng 19 onl`l saidr'column f base. The 'flower' surface 5 of Vthe column" base (Slisformed ot'=.convex 'sliape lor onl a, vcurve `centrally disposedrelatively' "to'saidcolumns Each coluinnhas lugs 10 "atV its flowercorners" which.'Y *iny the embodiment of' the'inventio'n illustrated,"are shown 'asY projecting downwardly; atv any `anglefo approximatelyA45 beyond ,the4 lower surface ofl the colnmn'base.

They said' lugs 10 are bored to `'receive' lheaded bolts 11- andsaidjbolts 'pass -throu'gh andprojecting 'soi'neivhatclips-"or'platesflQ which are held'thereon tacts the curved lowersurface of the column base." The side portions of the tension member lextend tangent to the curve at its central portion and at their' upperends are extended horizontally in contactv'ith the compression member 2,and at which point they are bolted to the ournal box in the usualstandard Way. The column hase, preferably, has a lugl or pin 15 whichenters a corresponding aperture torined in the center part of thetension meu'iber 8. The clips or plates 12 have outwardly projectinglugs v15 to which are connected, as by the rivets illustrated, the tiebars 11, which, at. their other ends, are connected tothebottoms ot thejournal bof-ies in the usual standard `Way.

The channel member 8 supports the spring 1 6, illustrated as tour innumber, on ivhich springs is supported the bearing or cap plate 17.' Thebearing pla-te -is formed with a: .plurality of transverse grooves inthis upper surface in. which are disposed the anti-friction rollers 18which carry the end vbodiment of the invention illustrated of the truckbolster 19, Which end is also lprovided with suitable grooves on itslower surface contacting said rollers. Thebearing plate 1T' haslaterally extending side portions or flanges 20 extending at each sideof the bolster columns l. and .there `is disposed between said plate andAeach ot said columns a Wear plate L1, rllhe .Wear rplate 21 hasoutwardly extending langes or is of channel shape so asto embrace thesides of theV columns t and .said plate is constructedfor verticalmovement. inthe emvthe said plate f2.1 has inwardlyprojecti .lugs 22which may conveniently be struck up therefrom and Which extend aboveandbelow the bearing plate 17, as clearly shown in Fig. 1. The Wearplates 21 thus move vertically with the hearing plate 17 and Contact thebolster columns 4;. Said bolster 19 has stop lugs 1S)n on its outer endadapted to engage Wear plates 21 to limit endivise move ment of saidbolster'.

In assembling the truck, one of the Wearing plates 21 is placed againstone column at the lowest point thereon While` the other Wearing plate isplaced against the other column in the highest position with thevtrucltholsters in place. T beinserted between the columns on an angleoit-about .475 when the lower ive ringplate can be moved into positionbetween the bolster and column, after which the springs .are placedunder the bearing plates 1T on the channel 8, Y

By the described construction, a very rigid and rugged column structureis provided to Inhichthe tension .member is easily secured. The tensionmember has onlytlie one curved bend at its central portion instead ofthe l .usual Millat central portion .ivitl-rtivo 'bends and the stressisi'lseat metralla dispose-.fl said.

he roller seat can now yvcolumns v.tangent to and in eontac tensionmember by the .curved surface on the column base. It will be noted thatthe tension member 3 is secured to the base G .bymeans which do notpierce the tension member but are disposed Wholly at the outsidethereof. By thus having no fastening means passing through the tensionmember the same is kept of unbroken cross section and is not weakened. tWill also be noted Vthat the rigid and integral structure of thecolumns, the connecting member at the top thereof and the base 6, tornian exceedingly rigid structure oi side vtrame and prevent any lateralmovement ot the column structure on the tension men'iber. Giving to theconvex loiver surface or the base G and the rigid column structure, thelatter cannot move longitudinally along` the tension member. There is,therefore, an intimate cooperation between the rigid integral columnstructure and the curved tension member.V

By the provision of thevvearing plate 21 embracing the bolster column, alarge Wearing .surface isobtained. The bolster bearing plate is stillguided on the bolster column and the increased Wearing surface betweenthe bolsterv and columns will greatly prolong the life of both. The Wear`does not come directly on the bolster and if the plate 21 becomesgreatly Worn,` a new plate can be substituted therefor with smallexpense.

From the above description it is seen that applicant has provided averysimple and improved st ructure ,of c 'ar truck. lt Will, of course, beunderstood, that various changes may be made in the form, details andarrangement ofthepa-rts yWithout de` parting. from the scope of'applicavnts .iniven` tion, which, generally stated, consists in a devicecapablerot carrying out the iobjects labove stated, such :as show-n anddescribed and set forth inthe appended claims.
